Package org.apache.avro.generic Description

A generic representation for Avro data.

This representation is best for applications which deal with dynamic data, whose schemas are not known until runtime.

Avro schemas are mapped to Java types as follows:

• Schema records are implemented as GenericRecord.
• Schema enums are implemented as GenericEnumSymbol.
• Schema arrays are implemented as Collection.
• Schema maps are implemented as Map.
• Schema fixed are implemented as GenericFixed.
• Schema strings are implemented as CharSequence.
• Schema bytes are implemented as ByteBuffer.
• Schema ints are implemented as Integer.
• Schema longs are implemented as Long.
• Schema floats are implemented as Float.
• Schema doubles are implemented as Double.
• Schema booleans are implemented as Boolean.
